mcp-creator

Create, build, and publish Python MCP servers to PyPI — conversationally.

Install mcp-creator, add it to your AI assistant, and it walks you through the entire process: naming your package, scaffolding a complete project, building, and publishing to PyPI.

Install

pip install mcp-creator

Setup

Add to Claude Code (~/.claude/settings.json):

{
  "mcpServers": {
    "mcp-creator": {
      "command": "mcp-creator",
      "args": []
    }
  }
}

Or for Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "mcp-creator": {
      "command": "mcp-creator",
      "args": []
    }
  }
}

Tools

Tool	What it does
get_creator_profile	Load your persistent profile — setup status, project history. Called first every session.
update_creator_profile	Save setup state, usernames, and project history across sessions
check_setup	Detect what's installed (uv, git, gh, PyPI token) — only walks through missing steps
check_pypi_name	Check if a package name is available on PyPI
scaffold_server	Create a complete MCP server project from a name + description + tool definitions
add_tool	Add a new tool to an existing scaffolded project
build_package	Run uv build on the project
publish_package	Run uv publish to PyPI
setup_github	Initialize git, create a GitHub repo, and push the code
generate_launchguide	Create LAUNCHGUIDE.md for marketplace submission

How It Works

1. Tell your AI what you want to build: "I want an MCP server that checks the weather"
2. It checks the name: calls check_pypi_name to verify availability on PyPI
3. It scaffolds the project: calls scaffold_server with your tool definitions — generates a complete, runnable project
4. You fill in the logic: replace the TODO stubs in services/ with your real API calls
5. Build & publish: build_package → publish_package → live on PyPI
6. Push to GitHub: setup_github creates a repo and pushes your code
7. Submit to marketplace: generate_launchguide creates the submission file with your repo URL

What Gets Generated

For a project named my-weather-mcp with a get_weather tool:

my-weather-mcp/
├── pyproject.toml         ← hatchling build, mcp[cli] dep, CLI entry point
├── README.md              ← install instructions + MCP config JSON
├── .gitignore
├── src/my_weather_mcp/
│   ├── __init__.py
│   ├── server.py          ← FastMCP + @mcp.tool() for each tool
│   ├── transport.py
│   ├── tools/
│   │   ├── __init__.py
│   │   └── get_weather.py
│   └── services/
│       ├── __init__.py
│       └── get_weather_service.py  ← TODO: your logic here
└── tests/
    ├── test_server.py
    └── test_get_weather.py

The generated server runs immediately — stub services return placeholder data so you can test before implementing real logic.

Requirements

• Python 3.11+
• uv (for building and publishing)

Development
